Just for the record, and in anticipation of our Summer Solstice reading, here is an easy way to determine what the sun's apparent elevation should be on that day.

Subtract Earth's declination of 23.55 degrees from your own latitude. Here at my location in MO it is 37.55 deg. N. Thus 37.55 - 23.5 = 14.05 deg. Now subtract that remainder of 14.05 from 90 deg., thus 90 - 14.05 = 75.95 deg. So if conditions are normal the sun should appear to be 75.95 degrees above the sun at noon on summer solstice at this particular location.

So, assuming we have sun that day, we'll get a reading of Sol's noon shadow, and from that shadow length, (which will be "x" in our formula), we can calculate the apparent elevation of Sol above the horrizon. The "y" in our formula will be the height of our steel pole, against which the sun casts a shadow, and that value is 64.75". Our little formula is "y/x", which = 64.75/shadow length. As soon as we plug in the sun shadow length obtained by observation on summer solstice, we can divide the formula out, giving us the "tangent". Next we look up in a trig book, in the trig tables in the back, to find what angle corresponds to our own calculated number. In this way, we can calculate the sun's actual apparent angle above the horizon, in order to determine if the actual angle matches the projected angle (what it should be).

We did not have sun on summer solstice, but did have good bright sun the day prior, and then today. Because of having a reading the day before solstice means we can come very close to approximating what the reading would be on the actual day of solstice.

The other piece of data gathered on solstice, and on all days where possible, is the length of the noon shadow. This data is being plotted on our multi-year graphs and there is another one coming soon. In fact, because of several factors, three graphs will be able to be overlapped and all photographed simultaneously, so as to show a curve similar to what is seen in an analemma. This multi-year graph will be posted within a few weeks--afer the last of the graphs is complete. It will be obvious to the reader, once the multi-year sun shadow graphs are posted, that currently, our sun shadow length is appearing to coincide neatly with prior years, particularly in the dates around solstice. Stay tuned.

Within a week or so, I'll be posting another five-year graph showing our other type of data: the length of Sol's 12 noon shadow. Plus, I plan show an overlap of three consecutive graphs, making for a more impressive curve. Stay tuned.

As promised, here is the near-solstice data. We cannot know exactly (from my observations) the reading on Summer Solstice, June 21, due to clouds here. But we do have the day before, so we can be this close.

As seen in post #345, we should observe the sun at noon on Summer Solstice at 75.95 degrees above the horizon when viewed at 37.55 degrees N. Due to clouds we could not obtain a reading, but on the day before, June 20, we measured Sol's noon shadow at 15.75".

Knowing 64.75" as the height of the pole against which the sun casts its shadow, and the shadow length of 15.75", we use our handy trigonometry. First we want a tangent, y/x, or 64.75/15.75, which gives us 4.111111. Then we look in the "trig tables" in the back of the book to see what angle corresponds with our tan of 4.111111, and we find 76 deg 19' 12" which is approximately 76.33 degrees above the horizon.

Since 76.33 deg. is slightly higher than 75.95 deg., it might mean the Earth's north south axis is slightly askew. But it might also mean my data is slightly errant. Then the third consideration is that we do not have a true Summer Solstice reading for 2019 due to clouds at this 37.55 deg. North location at noon. Had we gotten a reading that day it would have been very close to the reading for the 20th. That's about all that can be said about our Summer Solstice, 2019.

You're welcome. It should be mentioned that had I gotten readings exactly on the day of Summer Solstice, I would not have made approximations, and would not be rounding off here and there, as I may have in the past. Now is the time, especially on the exact day of solstice, winter or summer, to be as exact and precise as possible when doing calculations.

Only a few days until end of July when the "expanded" five-year graph of "noon-sun-shadow-length-plotted-against-date" graphs are posted here. Until then we have a few more bits of north-south axial line data gathered.

Recent observations:June 30, 2019, noon CST, north-south line pointed 6.0" left of left corner of csb (cornerstone base).July 2, 2019, noon CST, north-south line pointed 5.5" left of left corner of csb.July 4, 2019, noon CST, north-south line pointed 5.75" left of left corner of csb.July 5, 2019, noon CST, north-south line pointed 6.0" left of left corner of csb.July 13, 2019, noon CST, north-south line pointed 11.0" left of left corner of csb.July 18, 2019, noon CST, north-south line pointed 8.25" left of left corner of csb

New observations:July 23, 2019, noon CST, north-south line pointed 11.5" left of left csb corner.July 26, 2019, noon CST, north-south line pointed 8.125" left of left csb corner.July 27, 2019, noon CST, north-south line pointed 8.875" left of left csb corner.

These data points can be identified approximately in the attached pic. Stay tuned for more.

The pic(s) of the latest five-year graph plotting length of Sol's noon shadow, against date, represent three graphs overlapped, and if there had been space, I would have included a fourth--the very latest partial graph that includes August 12, 2019 data.

The curves of data points for years 2015 through 2019 show considerable conformity to each other, with several exceptions for 2016, 2017 and 2018 during the period of around May 14 through June 6, which can easily be spotted by just glancing along the left side of the curve. The lines are color coded (red=2015, blue=2016, black=2017, purple=2018, and green=2019) but where lines are in close proximity or overlapping it is almost impossible to discern among them. But when they are that close, it's obvious conformity.

The only thing that stands out in my mind currently is how the 2019 line throughout nearly the entire period shown, May 7 through July 31, is seen to be "running low", as it basically skirts the bottom or underneath side of the other lines. The differences are not great, but the consistency is something not seen so far, for this length of time.

What does it mean when the data points create a line that is lower on the graph than others? "Lower" on the graph means lower in relation to the y-axis, which represents the length of Sol's noon shadow. The longer the shadow, the lower in the sky the sun appears. Conversely, the higher the Sun's apparent elevation, the shorter the shadow, meaning the smaller the number on the y-axis. So, while the differences between yearly lines remain small, the graph does suggest that the overall apparent elevation of Sol for this time period in 2019 is slightly higher than for other years. Further, the same trend can be seen in the new graph beginning August 1 and including a data point for the 12th (not yet posted).

Stay tuned for more observations and stay tuned for pics in a few minutes. Am posting this without pics first, after the posting problem last night, and will add pics, one at a time.

Starting in 2020 will probably have to resort to using already-used color, but making dashed or dotted lines, as we're running out of ink colors, as I just do the originals with plain old ball point pen, a given color for a given year.

As we continue to move away from summer solstice, our days grow slowly shorter, and the direction in which Earth's axial north-south line points migrates slowly eastward for now.

Recent observations:

July 23, 2019, noon CST, north-south line pointed 11.5" left of left csb corner.July 26, 2019, noon CST, north-south line pointed 8.125" left of left csb corner.July 27, 2019, noon CST, north-south line pointed 8.875" left of left csb corner.

Haven't had a chance to compare these readings with years past, but will do so soon. In the meantime, there is another five-year graph ready to post, and am partway through the one after that, so stay tuned...
